How to generate rails new project with docker-compose

when i run command with $ rails new PROJECT with postgresql i realize struggle and tired that generate rails project files and setup database. if i got something wrong local environment such as rbenv, rvm on macOS or another OS. it's made me burnout.

docker-compose is perfect awesome developerment environment. when i generate rails project with docker-compose, i don't need any setup on local environment like ruby, rails version, database setup. docker-compose made easy setup rails project, database and another env.
